IMPROVEMENT I N CAR-LINK ADJUSTERS.

Specification forming part of Letters Patent No. 180,083, dated July 18, 1876; application filed June 3, 1876..

To all whom it may concern:

Be it known that I, GEORGE W. WILLIAM- SON, of Pittston, in the county of Luzerne and State of Pennsylvania, have invented a new and valuable Improvement in Link-Adjuster; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the let ters and figures of reference marked thereon. Figure -l of the drawings is a representation of longitudinal vertical section ot' my link-adjuster; and Fig. 2 is a transverse vertical sectional view, and Fig. 3 is a front view,

of the same. Fig. 4 is aside view, and Figs.

5 and 6' are detail views, thereof.

This invention consists in a car-coupling link-adjuster which is operated by a direct vertical lifting motion, without the use of side appliances, to enable the link to enter an opposite draw-head.

In the accompanying drawings, A designates a link; B, a draw-head; C, an ordinary coupling-pin; and D a device for adjusting the outer part of link A, so as to enable it to enter an opposite draw-head, which may be either higher or lower than draw-head B.

Link-adjuster D may be made in any one of several forms without departingfrom thespirit of my invention, and may be applied either inside of the draw-head B, or outside thereof", and it may be attached to said draw-head, or entirely separate therefrom but said link-adjuster must be capable of operation from the car-platform by a vertical movement ot"the operator, and withoutthe use of side attachments to the link or draw-head.

In Figs. 1 and 2 link-adjuster D consists of a bottom piece, cl, side pieces at, which are hinged thereto, and which are connected at the top by detachable bolts 0. ()n the inside of said pieces 61 are attached flanged plates (1 d, which grasp the opposite sides-0f link A within draw-head B, and operate to raise or depress the ou er end of said link, so as to make said link enter the opening in the opposite drawhead.

Side pieces 01 d move vertically on the outside of draw-head B, if an open draw-head is used, or in slots cut in the upper and lower sides of draw-head B, if a closed draw-head be used; and cross-bolts 0 make convenient handles for the grasp of the operator; or the upper ends of side pieces 61 may be so shaped as to answer the same purpose.-

Link-adjuster or grapple D is freed from eugagement with the link by detaching crossbolts 0, and turning back hinged arms 01 al until the flanged plates (1 d will pass freely up and down without touching link A. Said link is adjusted longitudinally by moving link adjuster D out or in, when the friction of flanged grappling-plates d 61 against the bot-, tom andsides of said link will carry it with said link-adjuster.

In place of the grapplinglink-adjuster D, p

as shown in Fig.1, I may use a modification. shown in Figs. 4, 5, and U.

E E, Figs. 4 and 5, designate two plate or sheet-metal arms, which arehooked or looped at their lower ends 6 0 about the link A, and which may be connected at their upper ends 6 e. Plates E E may be used to adjust link A longitudinally, or to elevate the inner part of link A, and thereby depress the outerpart of said link. F, Figs. 4 and 6, designates a device for elevating the outer part of said link and it consists of handle or bar f, and chain f, secured to both ends of said, handle, so asto form a loop below. This loop slips under the outer part of the linkA forthe purpose of lifting the same when the operator raises the cross-bar or handle f.

What I claim as new, and desire to secure by Letters Patent, is-

Link-adjuster'D, provided with hinged side arms d d and flanged grappling-plates 01 d substantially as and for the purpose set forth/ In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
